Description (partial)

Symptom:

Local MPLS labels change after an SSO causing a traffic drop a for 
short period of time.

Conditions:

The symptom is observed when LDP graceful restart is configured 
and SSO is supported on the platform. Only the prefixes which have a local label but not a remote label before the SSO are affected. After SSO, these prefixes get assigned a new local label. The traffic should recover once the LDP neighbors learned the new labels.
